EM Shield Compensation

This and the other three 'X Shield Compensation' skills (not to be confused with simple Shield Compensation) are low priority skills since they only benefit passive shield hardeners, which are very rarely used.

Explosive Shield Compensation

Kinetic Shield Compensation

Invulnerability Core Operation

Skill at operating the Rorqual's Pulse Activated Nexus Invulnerability Core module. Increases the effect duration and cycle time of the Pulse Activated Nexus Invulnerability Core by 10% per level.

A basic shield support skill (remember that an increase in shield capacity also increases the amount of shield hitpoints you recharge every second) which is an uncomfortably long train to V. But it is worth training to V in the long run. Level V is required for T2 Shield Boost Amplifiers.

Shield Operation

Skill at operating a spaceship's shield systems, including the use of shield boosters and other basic shield modules. 5% reduction in shield recharge time per skill level.

A useful fitting skill, makes squeezing some of the equipment used in shield tanking onto your ship easier.

Tactical Shield Manipulation

Skill at preventing damage from penetrating the shield, including the use of shield hardeners and other advanced shield modules. Reduces the chance of damage penetrating the shield when it falls below 25% by 5% per skill level, with 0% chance at level 5.

When your shields fall below 25% hitpoints damage begins to leak through to armor. This skill stops that happening. The exact mechanism of the 'leaking', and the consequent use or uselessness of Tactical Shield Manipulation, are subject to pedantic and rather irrelevant arguments; you need this skill trained to IV to use T2 active shield hardeners, so train it to IV and then forget about it.

Thermal Shield Compensation

This and the other three 'X Shield Compensation' skills (not to be confused with simple Shield Compensation) are low priority skills since they only benefit passive shield hardeners, which are very rarely used.
